The Democrats have flipped control of both the US House of Representatives and the Senate in a historic victory, bringing an end to Republican control of Congress. With control of both chambers of Congress, the Democrats now have an opportunity to deliver on the promises they made during their election campaigns, including their vow to challenge President Donald Trump and his administration. The House and Senate work together to pass legislation and approve government spending. However, neither chamber can act alone, and each holds distinct powers that serve as a check on the other. The Senate holds the unique power to approve Trump’s nominations of cabinet officials, ambassadors, and federal judges. With a majority in the Senate, Democrats can now block the president from appointing his allies to top government positions and force the White House to negotiate over legislation. A Democratic majority in the Senate also allows the party to launch investigations, demand documents, and summon witnesses to testify before congressional hearings. Among the issues Democrats have vowed to investigate are Trump’s family business dealings, including the dealings of Trump’s son, Donald Trump Jr., and his son-in-law Jared Kushner. Another investigation into Trump’s 2021 impeachment is also possible under a Democratic majority. In an interview with ABC News, House Democratic Leader Hakeem Jeffries said the party has not ruled out further action. Democrats could also use their control of Congress to challenge Trump's military agenda in Iran. While the administration can continue to use funds already approved for military operations, lawmakers could block or restrict further funding for the conflict. However, despite securing control of Congress, Democrats will still face significant obstacles in opposing the president’s agenda. Trump still has the power to veto legislation, which he has vowed to do with “everything” passed by Democrats. Major legislation in the Senate may also prove difficult to pass, as procedural hurdles such as the filibuster can require more than a simple majority.
When Sen. Chuck Schumer, D-N.Y., takes over as Senate majority leader, he should move to restore the filibuster back to where it was before the power of the minority to slow down the chamber was eroded by former Majority Leaders Harry Reid (a Democrat) and Mitch McConnell (a Republican). Both Reid and McConnell chipped away at the filibuster for immediate political advantage, but doing so damaged the Senate and hurt the country. ...
